W.I.S.D.O.M., n.d. By the time Ponce de Leon came ashore
near Sanibel Islands in 1513, Calusa culture was thriving.
Its people were divided into two distinct castes. Common
people worked at tasks ordered by the nobility. The Calusa
achieved a remarkable level of social complexity without
the benefit of agriculture. Although they eventually died
out due to the introduction of European disease, they
succeeded in keeping the Spanish at bay for almost two
hundred years.

By Robb Tiller, n.d. We are planning a trip to Cuba to trade
some Calusa artifacts for some of theirs as a cultural
exchange. Pine Island and its treasures [there are aspects
of this account that may offend some Native Americans].
